Description

Technical Field

[0001] This utility model relates to the field of paper collection technology in printing equipment, and in particular to a layered paper collection device. Background Technology

[0002] In printing plants, finished printed products need to be collected, stacked, and bundled for easy transfer, storage, and logistics. Generally, printing equipment is equipped with a paper receiving device. Most paper receiving devices (also known as paper stackers or paper stacking tables) can only collect printed products vertically and in a single manner. Each time the paper stack is completed, the machine needs to be stopped to remove the paper stack, which is relatively inefficient.

[0003] In the prior art, Chinese utility model patent with publication number CN220617837U and titled "A Layered Paper Collection Device" uses the up-and-down tilting motion of guide plates to change the conveying angle of the printed matter when conveying printed materials, so that the printed matter is conveyed to the upper or lower paper collection unit to complete the layered paper collection work.

[0004] This type of layered conveyor structure for printed materials requires precise delivery of printed materials to the upper and lower receiving units. This necessitates ensuring that the paper completely avoids the upper conveyor structure when the guide plate tilts downwards. However, as is well known, firstly, paper has a certain degree of rigidity, especially hardcover printed materials (brochures, pamphlets, etc.), which are difficult to bend with the downward tilt of the guide plate and thus smoothly enter the lower receiving unit. This necessitates making the guide plate very large, at least exceeding the size of typical printed materials. The layered receiving device needs to be longer and larger, which is detrimental to the efficient use of equipment space and may even cause the equipment size to exceed width and height limits, affecting handling and logistics. Secondly, the high conveying speed of printed materials may cause them to drift directly off the tilting guide plate due to inertia, failing to enter the lower receiving unit, easily leading to misdelivery or blockage. Therefore, existing layered receiving devices have certain inconveniences in use. Utility Model Content

[0005] The purpose of this utility model is to provide a layered paper receiving device to solve the problems of inconvenience in the use of existing layered paper receiving devices, such as low effective utilization of equipment space and easy occurrence of incorrect or blocked printed materials.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A layered paper receiving device includes a frame and a paper conveying mechanism, a paper transfer mechanism and a paper receiving mechanism, all mounted on the frame.

[0008] The dynamic paper output end of the paper conveying mechanism is adapted to the paper feed end of the paper transfer mechanism and the paper feed end of one of the paper receiving mechanisms.

[0009] The paper delivery end of the paper transfer mechanism is adapted to the paper inlet end of another of the paper receiving mechanisms;

[0010] The paper conveying mechanism includes a telescopic cylinder, a fixed plate, a fixed roller, a paper feeding roller, and a paper pressing roller. The fixed roller is rotatably mounted on the frame. The two fixed plates are symmetrically arranged and rotatably connected to both ends of the fixed roller. The two ends of the telescopic cylinder are respectively hinged to the frame and the fixed plate. The paper feeding roller and the paper pressing roller are both rotatably mounted on the fixed plate. A dynamic paper output channel is formed between the fixed roller, the paper feeding roller, and the paper pressing roller.

[0011] A further technical solution is that the minimum roller distance between the fixed roller, the paper feeding roller, and the paper pressing roller is the same.

[0012] A further technical solution is that the frame is also equipped with a paper pressing belt conveyor that corresponds one-to-one with the two paper receiving mechanisms.

[0013] A further technical solution is that the paper transfer mechanism is a belt conveyor.

[0014] A further technical solution is as follows: the paper receiving mechanism includes a paper receiving platform, a fork platform, a rodless cylinder, a load-bearing plate, a slider, a lead screw, a motor, and a paper-blocking assembly. The paper receiving platform is inclinedly mounted on the frame. The fork platform is mounted on the movable end of the rodless cylinder and is adapted to the paper receiving platform. The rodless cylinder is mounted on the load-bearing plate. The load-bearing plate is mounted on the slider. The slider is threadedly connected to the lead screw. The lead screw is rotatably mounted on the frame. The motor is mounted on the frame, and the power output end of the motor is connected to the lead screw via a transmission structure. The paper-blocking assembly is mounted on the frame and is adapted to the fork platform.

[0015] A further technical solution is: the paper-blocking assembly includes a first cylinder and a fork plate, the first cylinder is mounted on the frame, the fork plate is mounted on the power output end of the first cylinder, and the fork plate is adapted to the fork platform.

[0016] A further technical solution is that a pusher plate driven by a second cylinder is slidably installed in the groove of the paper receiving table.

[0017] A further technical solution is: a tilting table adapted to the paper receiving mechanism is rotatably mounted on the frame, and the tilting table and the frame are respectively hinged to both ends of the third cylinder.

[0018] A further technical solution is: a baffle plate is slidably installed on the flipping table, and the baffle plate is connected to the power output end of the fourth cylinder.

[0019] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0020] This invention proposes a layered paper receiving device. This device can use a paper distribution mechanism to precisely control the conveying direction of printed materials, regardless of the hardness, size, or conveying speed of the printed materials. This ensures that the paper receiving mechanism can accurately collect its corresponding printed materials and achieve high-speed production. Moreover, the two paper receiving mechanisms do not interfere with each other. That is, while one paper receiving mechanism is carrying out the paper stacking process, it does not affect the paper stack removal and bundling work on the other paper receiving mechanisms.

[0035] Example 1:

[0036] This implementation example Figure 1 , Figure 2 and Figure 3 As shown, a layered paper receiving device includes a frame 1 and a paper conveying mechanism 2, a paper transfer mechanism 3 and a paper receiving mechanism 4, all mounted on the frame 1.

[0037] The dynamic paper output end of the paper conveying mechanism 2 is adapted to the paper feed end of the paper transfer mechanism 3 and the paper feed end of one of the paper receiving mechanisms 4.

[0038] The paper feed end of the paper transfer mechanism 3 is adapted to the paper feed end of another paper receiving mechanism 4;

[0039] The paper conveying mechanism 2 includes a telescopic cylinder 5, a fixed plate 6, a fixed roller 7, a paper feed roller 8, and a paper pressure roller 9. The fixed roller 7 is rotatably mounted on the frame 1. The two fixed plates 6 are symmetrically arranged and rotatably connected to both ends of the fixed roller 7. The two ends of the telescopic cylinder 5 are respectively hinged to the frame 1 and the fixed plate 6. The paper feed roller 8 and the paper pressure roller 9 are both rotatably mounted on the fixed plate 6. A dynamic paper output channel is formed between the fixed roller 7, the paper feed roller 8, and the paper pressure roller 9.

[0040] It should be noted that the device is equipped with an industrial controller and sensors, such as a material sensor adapted to the paper receiving mechanism 4 installed on the frame, and a photoelectric counter set at the paper feeding mechanism 2. The material sensor is used to provide feedback on the material status on the paper receiving mechanism 4, and the counter is used to identify the amount of material fed each time, so as to achieve the purpose of accurately controlling the paper receiving work.

[0041] The working process of this device is as follows: Printed materials or paper arrive at the sheet distribution mechanism 2 via an external conveyor. First, the controller on the sheet receiving device, based on the signal feedback from the material sensor on the receiving mechanism, identifies the paperless receiving mechanism, which prepares for paper collection. Then, the telescopic cylinder 5 on the sheet distribution mechanism 2 rotates the fixed plate 6, thereby controlling the direction of the dynamic paper output channel between the feeding roller 8 and the pressure roller 9. The printed materials are constrained and guided by the dynamic paper output channel, precisely controlling the conveying direction and posture of the printed materials, allowing for smooth sheet distribution regardless of the hardness, size, or conveying speed of the printed materials. This ensures that the receiving mechanism can accurately collect its corresponding printed materials and achieve high-speed production. Finally, the printed materials are conveyed towards the paperless receiving mechanism, entering the sheet distribution mechanism via the conveyor belt and then the paperless receiving mechanism, where the paper stacking process is completed. This process does not affect the removal and bundling of paper stacks on other receiving mechanisms.

[0042] It is worth noting that the fixed roller 7 of the paper conveying mechanism 2 remains stationary and is always flush with the external conveyor.

[0043] It is worth noting that: Figure 3 As shown, the fixed roller 7, the paper feed roller 8, and the paper pressure roller 9 are triangular in shape, meaning that the fixed roller 7 and the paper feed roller 8, as well as the paper feed roller 8 and the paper pressure roller 9, can all form paper output channels. When the telescopic cylinder 5 drives the fixed plate 6 to rotate at a small angle, the printed matter can pass through either of the two paper output channels. Moreover, the angles of the two paper output channels differ greatly, achieving the amplification effect of micro-rotation and paper conveying direction.

[0044] Preferably, the minimum roller distance between the fixed roller 7, the paper feed roller 8, and the paper pressure roller 9 is the same.

[0045] With the fixed roller 7 and the paper feed roller 8, as well as the paper feed roller 8 and the pressure roller 9, all forming paper output channels, it is ensured that printed materials of the same specification can pass smoothly through any paper output channel.

[0046] Preferably, the frame 1 is also provided with a paper pressing belt conveyor 10 corresponding to the two paper receiving mechanisms 4.

[0047] The paper pressing belt conveyor 10 consists of multiple belt rollers and thin belts tensioned on the belt rollers. The active belt roller is driven by a motor to rotate, pressing the paper passing under the paper pressing belt conveyor 10, preventing the high-speed paper from floating, and also playing a certain guiding role.

[0048] Preferably, the paper transfer mechanism 3 is a belt conveyor.

[0049] The belt conveyor is equipped with a rotatable boat-shaped paper press to press down the paper passing over the belt conveyor and prevent the high-speed paper from floating.

[0050] Example 2:

[0051] Based on the above embodiments, this embodiment, for example Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the paper receiving mechanism 4 includes a paper receiving platform 11, a fork platform 12, a rodless cylinder 13, a load-bearing plate 14, a slider 15, a lead screw 16, a motor 17, and a paper blocking assembly 18. The paper receiving platform 11 is inclinedly mounted on the frame 1. The fork platform 12 is mounted on the movable end of the rodless cylinder 13 and is adapted to the paper receiving platform 11. The rodless cylinder 13 is mounted on the load-bearing plate 14, and the load-bearing plate 14 is mounted on the slider 15. The slider 15 is threadedly connected to the lead screw 16. The lead screw 16 is rotatably mounted on the frame 1. The motor 17 is mounted on the frame 1, and the power output end of the motor 17 is connected to the lead screw 16 through a transmission structure. The paper blocking assembly 18 is mounted on the frame 1 and is adapted to the fork platform 12.

[0052] Before paper is received, motor 17 drives lead screw 16 to rotate, thereby adjusting slider 15 and its components (fork 12, rodless cylinder 13, and load-bearing plate 14) to rise together, moving away from paper receiving table 11. The position of fork 12 is adjusted using rodless cylinder 13, specifically, by adjusting the distance between the head of fork 12 and the paper stop assembly 18 to accommodate the size of the printed material or ensure that the printed material falls completely onto the head of fork 12. Then, the paper falls one by one and continuously onto the head of fork 12. Because fork 12 is tilted and has paper stop assembly 18 at its lower end, the printed material... Under the influence of gravity, the paper stacks align upon landing. As the paper stacks on the forklift 12 rise, the motor 17 drives the lead screw 16 to rotate, controlling the forklift 12 to descend until the printed materials collected on the forklift 12 meet certain requirements (such as quantity, height, or weight requirements, with corresponding sensors collecting the relevant information). At this point, the forklift 12 returns to the receiving table 11. Under the action of the rodless cylinder 13, the forklift 12 moves away from the paper-blocking assembly 18, thereby placing the paper stacks on the receiving table 11 to complete the paper collection process. When using other paper collection mechanisms 4 without paper, the collected paper stacks can be removed.

[0053] Preferably, the paper-blocking assembly 18 includes a first cylinder 19 and a fork plate 20. The first cylinder 19 is mounted on the frame 1, and the fork plate 20 is mounted on the power output end of the first cylinder 19, and the fork plate 20 is adapted to the fork platform 12.

[0054] Driven by the first cylinder 19, the fork plate 20 is lifted, passes through the gap on the fork platform 12 and rises, serving to stop the paper and align it.

[0055] Preferably, a pusher plate 22 driven by a second cylinder 21 is slidably installed in the groove of the paper receiving table 11.

[0056] After the corresponding paper receiving mechanism 4 completes the paper stacking, the pusher plate 22 can be driven by the second cylinder 21 to slide in the groove of the receiving table 11 to push the paper stack out of the paper receiving mechanism for easy paper retrieval.

[0057] Preferably, a tilting table 23 adapted to the paper receiving mechanism 4 is rotatably mounted on the frame 1, and the tilting table 23 and the frame 1 are respectively hinged to both ends of the third cylinder 24.

[0058] The paper stack in the paper receiving mechanism 4 can be pushed to the tilting table 23. At this time, the paper stack is in an inclined state. The third cylinder 24 is used to level the tilting table 23 and straighten the paper stack.

[0059] Preferably, a baffle plate 25 is slidably mounted on the tilting table 23, and the baffle plate 25 is connected to the power output end of the fourth cylinder 26.

[0060] The fourth cylinder 26 drives the baffle plate 25 to block the tilted stack of paper on the flip table 23.

[0061] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
